New developments show that the shooter from this past weekend's shooting in Jacksonville was a participant in a similar tournament for the popular NFL video game Madden in Buffalo last year.

According to EA Sports (the game's maker), the winner of last year's "Buffalo Bills Championship Challenger" is listed as David Katz.  It was a tournament that took place at (716) Food and Sport.

WIVB says they partnered with their sister stations in Jacksonville and Baltimore to confirm that the David Katz that won the tournament here in Buffalo is the same one who was responsible for the Jacksonville shooting.

According to Total News Wire, the shooting occurred at a bar called GLHF Game Bar at Jacksonville Landing, killing two people (3 including the gunman) and injuring 9 others.

The search for a motive in the shooting is still under investigation.
